Abstract: A ski pole handle which includes a main gripping portion defined by an upstanding elongated body having upper and lower body portions, opposite inboard and outboard lateral faces and opposite forward and rear faces; a generally tubular thumb-receiving channel disposed at the upper body portion, the elongated body defining a handle portion disposed beneath the thumb-receiving channel and being adapted to accommodate and be gripped between a skier's fingers and palm, the thumb-receiving channel having an inner bottom thumb-supporting generally convexly curved surface merging with the rear face whereby a person's thumb and particularly the phalanges, metacarpus and the associated ulnar collateral ligament of the metacarpophalangeal joint are protected against injury normally attributed to abduction/extension of the thumb which is the usual cause of typical collateral ligament injury resulting from a skiing fall, a pair of laterally outboard knuckle-protecting sheets, one ascending and depending to collectively d

Abstract: This disclosure relates to an atrioventricular electrode for the purpose of electrically stimulating the heart, for example, in conjunction with a pacemaker. The atrioventricular electrode includes a ventricular component and an atrial component, both carried by a common body. The atrial component, in its original form assumes a generally J-shaped configuration so that it may hook onto the atrial appendage at the time the ventricular component has the electrode thereof firmly engaged against the right ventricular wall. Restraining means are provided for, during the insertion of the atrioventricular electrode to restrain the atrial component in a substantially straight line relationship adjacent the ventricular component so as to facilitate the insertion of the atrioventricular electrode.
